. ZMy invention relates to :asingle blank collapsible carton'bhaving a recessed automatic. bottom. Thisycarton may .be completely manufactured by automatic machinery, ;shipped' to -the .'user in collapsed condition, loaded into a packing machine and automatically erected to articlei-receivin g'position. This application is a division. of my application Serial No. 496,1 11,.filedMarch 23, 195 andentitledfRecessed Automatic Bottom Carton," 'now 'Patent No. 2,866,588,

granted DecemberSO, 1958.

. jWhile automatic bottoms have been employed in cartons for a"'number of years, the" instant invention provides an automaticallyerectablecarton which includes a recessed automaticbottom suitable for the resilient support of fragile articles, such as sealed beam headlights and the like, which may be placed in the carton with their most fragile portion restingon the bottom and through the recessed construction be protected from damage due to shock and rough handling.

Further, it is possible with this carton to provide a I chest-like carton with a leg structure which may be utilized for packaging candy and the like without any possibility of creating misconception as to the amount of candy held within since the leg structure and raised bottom are immediately apparent.

Other objects and meritorious features of the invention will be apparent from the following description taken in conjunction with the drawings wherein like numerals refer to like parts throughout the figures and wherein:

Fig. l is a perspective view of a chest-type carton in erected condition which embodies the invention;

Fig. 2 is a perspective view of the chest-type carton of Fig. l in collapsed condition;

Fig. 3 is a plan view of the single blank from which the carton of Figs. 1 and 2 is made;

Fig. 4 is a perspective bottom view of the carton of Fig. l; and

Fig. 5 is a plan view of a portion of a single blank of modified design.

Referring now to Figs. 1-4, it will be seen that the chest carton is made from the single blank of Fig. 3 which is cut and scored to form four outer walls 15, 16, 17 and 18, and an upper end attaching member 19 and a lower end attaching member 14. Glue areas are indicated on the blank. Y

To provide a carton having the same surface of the blank showing at the inner walls and the outer walls, inner wall panels 20, 21, 22 and 23 extend downwardly from the outer-walls -18 and are glued in face-tmface engagement therewith.

The recessed bottom is formed in part by means of Patented July 5, 1 960 mitting tabs 32 and 33 form an automatically erectable and collapsible recessed bottom.

The bottom folding tab 32 is integrally hinged to the hinge edge 34 of'the bottom member 28, this hinge. edge 34 defining .45-degree angles, when the carton is in erected condition, with the upper edges35 and 36 of the bottom four bottom recessing panels 24, 25, 26' and 27 which extend upwardly from the bottom edges of the outer walls 15-18 and are glued in face-t0-face engagement therewith. Four bottom members 28, .29, 30 and 31 arehinged to the upper edges of the recessing panels 24-27 and these bottom members 28-31 in cooperation with the two diagonally opposed bottom folding motion transi It willube noted thatthefbottom members as. and so are'jtriangular in configuration and 2 that glue areas. 40 and 41% on the' blank-are shown on the rectangularbottom members 29 and 31 for the bottomfoldingltabs 32 and 33, respectively, 1

The edge. 42 of the inner-wall .panel 20 is cut to enable adherenceiof the upper attaching member 19 to.the inner face of .the outer wall'15zabove the bottom members 28-. 3l,j EI,he lower attaching member is. afiixed to.the bottomrecessing-member 24 below the bottom members The .recessed ,,bottomz ofthe instant invention enables the. provision of a partially open. supporting framework i beneath the bottom. members 28-31 by forming openings by matingcutouts inthelowerporti onsjof the outer IS-IB' and the adjacent portions" of recessing members 24-27. In the embodiment shown in Figs; 1-4, elongated openings 43, 44, 45 and 46 are formed on either side of and including a portion of the score lines between the outer walls 15-18 and the recessing members 24-27, these openings 43-46 being positioned intermediate the side edges of the outer walls 15-18 and recessing members 24-27. This construction results in the formation of double thickness corner legs 47, 48, 49 and 50 (Fig. 4), each of which comprises two sections at right angles to each other with the outer wall thickness of the legs being uncut to present a tailored appearance as well as a rigid construction.

In Fig. 5 is shown a modification wherein an upper surface member 51 extends from the inner wall 23, this surface member 51, upon erection of the carton, providing a top cover over the elements of the automatic bottom which has a visible surface of the same material as the outer wall surface of the carton. This modification improves the tailored appearance of the carton without requiring the use of separate parts or a blank stock having expensive surface material on both sides.

The collapsed carton of Fig. 2 may be erected by automatic carton loading machinery which applies pressure on the side edges of the flattened carton in the direction of the arrows as shown. Various portions of the blank are cut-away to facilitate assembly and reduce erection stresses. Stapling, stitching, and the like, as well as gluing may be employed to fixedly secure the panels in proper relation.

Various modifications within the spirit of this invention will be apparent to those skilled in the art and for that reason I wish to limit myself only within the scope tion of the carton, four bottom: recessing panels, each hingedly connected to the bottom edge of one of said outer walls and extending upwardly from the bottom edge in fixed face-to-face relation to the inner face of the corresponding outer wall to provide a double thickness leg at -the base of each of the said four outer walls, and four bottom flaps each hingedly connected to the upper edge of a bottom recessing panel, each of an opposed pair of :said :bottom .flaps having a diagonal ."fcxld'lline which divides the flap into a part which is hinged "to The respect'we rbottom :reoe'ss'ing panel and a motionitrans- :mitting tab :afl ixed in iface-tod ace relation withiazn iadj'aremove 'coterminous portions of the outer wall and the recessing panel hinged thereto -to define spaced-apart supporting legs at the corners, and four bottom flaps each hingedly connected to the upper edge of a folded-back recessing panel, each of an opposed pair of said bottom flaps having 'a diagonal fold line which divides the flap into a part which is hinged to the respective bottom recessing panel and a motion-transmitting tab .aifixed in face-to-face relation with an adjacent bottom 'fiap, the diagonal fold lines of .each ofthe opposed pair of :said bottom flaps being :at :an angleof 45 degrees to .the hinge connecting the bottom flap and the corresponding bottom 7 recessing panel,saidUmotion-transmitting stab ,permitt'ing four rectangular outer walls permanently hingedly eonto each -'other.in the aerectedacondifion of the carton, four folded-back bottom recessing panelsof equalheight; *each hingedly connected to the lower edge of eone'of 't he' outer walls and extending upwardly from the bottom edge in fixedface-to-face relation to the inner fac'e'of the correspending outer wall 'to' provide, a double'th'iclmess'wall between the 'hinge line and the recessed bottom, at least on'eiofsaid double thickness walls being cut away to the motion-transmitting zfiap to be fielded against itheflap to which it-is hinged in the collapsed condition of the carton serving to erect the two adjacent bottom flaps when the corresponding outer walls are pivotally separated from collapsed condition.

3.. A single blank, self-erecting carton as set forth in claim '2 wherein at least onepair of :opposed bottom flaps are-of predetermined size to provide a surface-coextensive with the area de'fined within the four outer walls. 1
